Kev,
I would ask around the club and see if you can find someone who will let you "test drive" before you buy. It's also worth doing the test with whichever check pilot you are intending to fly most with (if you have a strong preference that is) - the Tiger's intercoms can be fine with some combinations of headsets and awful with others.
Also, although it's a big hit, it might be worth looking at a helmet. A number of the Turb Team wear them and it would make sense, if there is any chance that you will want one in the future, to get it now - thus saving the expense of the cloth/leather version. It won't look out of place (as long as you don't wear it in the Cub or Jodel
).
